Performance Analysis of Python’s dict() and {}
Some time ago, during a code review, I had a discussion with a colleague of mine about preferring dict() over {} in
new Python code. They argued that dict() is more readable — and expresses intent more clearly — therefore should
be preferred. I wasn’t convinced by that, but at that time I didn’t have any counterarguments, so I passed.
Yet that made me wonder: what’s the difference between the dict type and {} literal expression?
